Dynamics of entropy and information of time-dependent quantum systems: exact results

  title={Dynamics of entropy and information of time-dependent quantum systems: exact results},
  author={K. Andrzejewski},
Dynamical aspects of information-theoretic and entropic measures of quantum systems are studied. First, we show that for the time-dependent harmonic oscillator, as well as for the charged particle in certain time-varying electromagnetic fields, the increase of the entropy and dynamics of the Fisher information can be directly described and related. To illustrate these results we have considered several examples for which all the relations take the elementary form. Moreover, we show that the… Expand
